SHUTTER-SLAT HOLDER.

SPECIFICATION forming part of Letters Patent No. 637,949, dated November`:28, 1899. Application led August 26, 1899. Serial No. 728,608. (Nomodel-i) To a/ZZ whom t may concern:

Be it known that I, WILLIAM G. SMITH, a citizen of the United States,residing at Garwin, in the county of Tama and State of Iowa, haveinvented a new and useful Shutter-Slat Holder, of which the following isa specification.

This invention relates to that class of shutters comprising a framehaving slats pivoted therein, and more particularly to means for holdingthe slats closed and at different angles of adjustment, the object ofthe invention being to provide a device of this nature which will besimple and cheap in its construction and at the same time eective inoperation. g

In the drawings forming a portion of this specification, and in whichlike numerals of reference indicate corresponding parts in the severalViews, Figure 1 is a front elevation of the lower portion of a shutterwith the slatholder in position to hold the slats closed. Fig. 2 is asection on line 2 2 of Fig. 1 and showing the holder in side elevation.Fig. 3 is a detail section showing the holder and its attachment to theconnecting-rod of the slats. Fig. 4 is a view similar to Fig. 3 andshowing the holder in its position when holding the slats at the pointof their greatest opening. Fig. 5 is a detail perspective of the holder.

Referring now to the drawings, the holder consists of a plate 5, adaptedfor attachment to the frame of a shutter, below the slats thereof, andwhich plate has struck up therefrom adjacent the upper edge parallelears 6. Pivotally connected with these ears is a casing 7, consisting ofa plate having its side edges bent to lie parallel and having its di-Ininished end 8 bent to lie between these parallel portions, although itwill be of course understood that, if desired, this casing may be formedintegral by casting. In the web or back 9 of the casing is formed a slot10, through which is projected a stem l1, having a head 12, for purposesto be presently explained. The inner end of the stem 11 is provided witha lateral projection 13, upon which is disposed a helical spring 14, theopposite end of which lies in a seat 15 at the end of the casing, andwhich seat is formed by bending the free end of the portion 8 inwardly,as shown in Figs.

wardly a web 17, connected with which is a plate 18, the sides of whichare bent to lie parallel and at right angles to the plate on one sidethereof, the plate 18 and said parallel portions forming in effect asecond casing, which is pivotally connected with the sides of thefirst-named casing through the medium of the pivot pin 19, passedlaterally and through the adjacent portions of the parallel sides of thecasings. The plate 18 lies in a plane parallel with the socket G, andboth are practically of spring metal in order that the socket may becaused to snugly receive the connecting-rod of the several slats of theshutter and that the parallel side portions of the plate 18 mayfrictionally engage the adjacent portions of the first-named casing andhold the two casings frictionally at various angles.

The pivot-pin 19 is so located that when the casings are moved to lie ina common line' the plate 1S will lie snugly against the back 9 and willlie beneath the head 12 of the pin 11, the

lplate 1S in its movement upon the pivot 19 engaging the head 12 of thepin and moving it/ rearwardly against the tendency of the spring 14until said plate has passed beneath the head, when the spring will actto throw the head forwardly to the positionshown in Fig; 3 to enter theedge of the plate 1S in a slot 2O in the pin or stern 11 below the head.

In practice, as shown in Figs. 1 and 2 of the drawings, the plate 5 issecured to the bottom rail of the shutter-frame and in such a positionthat the socket 16 may receive the shifting-bar 2l of the shutter-slats22 and that when the casings are in a position shown in Figs. 1, 2, 3,and 5 the holder will maintain the shifting-rod in'its uppermostposition to hold the slats of the shutters closed.

When it is desired to open the slats, the pin or stem 11 is. drawndownwardly to release the engaged end of the plate 18, after which theplates may be moved upon their pivots to the position shown in Fig. 4Eto hold the slats at their points of greatest opening. Then it isdesired to again close the slats, it is only ICO.

- wardly and permit the second casing to ennecessary thattheshifting-bar be Ymoved npwardly,when the plate 18 will operate thelatch to permit engagement with the slot 20.

It will of course be understood that in practice the several parts ofthe holder may be cast or stamped and that the materials and proportionsthereof may be varied as desired.

lVhat I claim isl. A Slat-holder, comprising a plate having ears, acasing pivotally connected with .the ears and having a slot therein, abolt Within the casing an'd projecting outwardly thereof through theslot, a recess in the bolt between the casing and the outer end of thebolt, a spring adapted to hold the bolt normally in a predeterminedposition, and a second casing pivoted'to the first-named casing andhaving a socket for the receptionof a shift-rod, said casing beingadapted for engagement with the outer portion of the bolt to move thebolt reargage the recess of the bolt.

, 2. A Slat-holder, comprising a plate having ears, acasing pivoted tothe ears and having a slot, a bolt slidably disposed in the slot andprojecting outwardly thereof, a recess in the bolt extending into theoutwardly-projecting portion, a projection upon the inner end of thebolt, a sprin g engaging the projection and adapted to hold the boltyieldably in a predetermined position, and a second casing having asocket for the reception of a shift-rod, said casing being pivoted tothe first-named casing and adapted to initially engage the outer end ofthe bolt and move it rearwardly to permit the casing to enter the recessof the bolt.

In testimonj7 that I claim the foregoing as my own I have hereto affixedmy si gnature in the presence of two Witnesses.
